I just got back from Utila after staying at Laguna Beach and had an amazing time. Not only was the diving great (we got to snorkel with a 20 ft whale shark), but the lodging was just what I was looking for. There was ample opportunity to socialize with other divers in the dining area/bar if you wanted, but the rooms were very private, air conditioned, and clean.
The management and staff were very friendly and approachable. Soledad and Matias were the two managers on duty while I was there and set me up with horses to ride, rides into town for nightlife, and even offered me special needs options for food. The bartender, Josue, was great and makes a phenomenal fresh pina colada, and also owns a bar in town if you happen to want to venture there. The boat captains were almost as enjoyable as the diving. The three I met, John, Kerry, and Wagner, were all characters. I never rode a boat with Wagner, but enjoyed many laughs with him as we were waiting for the boats to take off. John piloted us to the whale shark and has many interesting stories to tell. Kerry has an infectious laugh and showed us around the cayes around the island and even took us to his mothers house for a delicous home cooked meal. It was an amazing experience. As you can tell, I have nothing but good things to say about everyone I met there.
About the diving: The structure was pretty standard for dive trips; There was always an opportunity for 3 boat dives with the option of a 4th drop off dive every afternoon and night dives 2 times a week. We basically saw all the aquatic life you could hope to see in the Carribean (whale sharks, eel, octopus, turtles, rays, seahorses, batfish, toadfish, etc. Not to mention all the small juvenile fish and all the small coral life) and I was not at all disappointed at any of the sites we dove at.
As far as getting to Utila, there was a prop plane that took us there-- I don't remember the individual cost because they just put it on the bill. However, if you are more adventurous than I was, or you have a larger group, there were lots of boats in town that offered to take me to Utila for anywhere between 50 to 100 bucks a trip-(not per person!)
So, I hope the encyclopedia I just wrote answers your questions. Feel free to ask any more specifics.
